Best Use:

When charging gear with the Yeti 400 Lithium, take note of the LCD Battery Display. If you plug in devices that have a high power requirement (a large refrigerator), the charge level of the Yeti can drop very quickly and you may not get exactly 400Wh of energy. Also, especially when using the AC power output, the Goal Zero Yeti will be converting the energy from the DC power of the battery to the AC power needed by your device. Although your Goal Zero Yeti has a highly efficient inverter, there is still some energy lost in the conversion and you will not get the full rated capacity of the battery.

For Use in Cold Weather:

Cold temperatures (below freezing) can impact the Yeti's battery capacity. If you'll be living off-grid in sub-zero conditions, we recommend keeping your Yeti 400 Lithium in an insulated cooler, connected to a power source (solar panels), and charging your gear. The natural heat generated by the Yeti 400 Lithium contained in an insulated cooler will keep battery capacity at its highest.

Storage and Maintenance:

Having your Yeti 400 Lithium connected to a power source, like a solar panel or wall outlet, between adventures or while in storage keeps its battery healthy and topped off. This prolongs battery life and will ensure your Yeti 400 Lithium is charged and ready to go all day, every day. If you can't keep the Yeti 400 Lithium plugged into a power source during storage, fully-charge your Yeti 400 Lithium every 10-12 months and store in a cool, dry place. Failure to maintain the Yeti 400 Lithium by following these steps can result in battery damage which will void the product warranty.
